ROBERT C. SNOVDEN, OF ELIZABETH, PENNSYLVANIA.

SHINGLE.

To aZZ whom it may concern:

Be it known that 1, ROBERT C. Snowman, of Elizabeth, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Shingles, of which the following is a description.

In the drawings, Figure 1 is a perspective view showing a section of roof constructed of my shingles, the lateral flanges being indicated in dotted'lines. Fig. 2 is a top plan view of one of the shingles. Fig. 3 is a cross-see tion thereof on line a: as, Fig. 2; and Fig. 4 is a section 011 line 3/ y, Fig. 2, all of which will be described.

The object of my invention is to provide a shingle that will combine ornamentation with strength and will be easy of application and removal, and will, when in use, permit the ventilation of the roof, as well as its expansion and contraction under the influence of heatv and cold, as is desirable.

To these ends the invention consists in the novel construction of the shingle, as will be hereinafter described.

The shingles are formed from plates A of metal, usually of tin, of suitable size. One edge of this plate is bent upward at right angles, forming the upright flange or wing B. The edge opposite upright B is bent upward at right angles and then back, forming a keeper. 0, fitted to rest over the upright B of an adjacent shingle. These parts B and O interlock in the formation of the roof, for which reason, and for convenience of reference, I term them interlocking portions. The edge of the plate is extended at a beyond the keeper 0, forming extension D, and is lapped up therein and carried down to a point in the plane of the plate A, where it bends and pro- 0 jects laterally outward in the flange portion,

which is utilized to receive the nails or tacks by which the shingles are secured. By means of this flange the nails are hidden from View and the necessity of detached fastening-straps and similar expedients is obviated. It is preferred to terminate the flange D at one end short of the end of the shingle-plate in order that such end may serve as a stop against which the adjacent shingle abuts, and a guide SFECIFICATION forming part of Letters Patent No. 339,945, dated April 13, 1886.

bywhich said shingle is stopped in proper place.

In the formation of the roof it will be under stood the upright B of a particular shingle fits up in the keeper of the meeting shingle to the left. The shingle above the said particular one referred to laps at its lower edge down thereon, its keeper fitting over that of the said shingle, in which case it will be seen the lower edge of its lateral flange will abut the upper edge of the keeper of the particular shingle.

The operation of forming the roof from the shingles will be understood from above de- Scription. The shingles are formed with a central struck-up portion, E, which may be of any suitable design, but is preferably as shown. It is usual to form this portion with a flat top and beveled sides, as most clearly shown in Figs. 3 and 4. At its opposite ends the shingle has struck-up portions F and G, the former being usually set slightly in from the edge of the shingle and the latter opening out of such edge. These portions F and G are conformed to each other, so that in lapping one shingle over the upper edge of a lower one the portion G of one shingle will fit on and partially over the portion F of the lower shingles. These struck-up portions ornament and-iniprove the appearance of the shingles, and in addition operate to strengthen the same and increase the ventilation of the roof. These struck-up portions also facilitate the painting of the roof in fancy patterns conforming to such portions, which latter, as is manifest, will serve as guides in such painting.

It will be noticed that a roof constructed of my shingles, as described, will afford the desired ventilation, as well as permit expansion and contraction under the influence of heat and cold.

Obviously my shingles may be applied by unskilled workmen and will not require the services of a practical roofer. These shingles it will be seen may be packed and shipped to any desired point by boat or rail, being convenient to handle and taking up but small room in storage.

It will be noticed that the upper struck-up 20 forth;

portions, F, of my shingle are depressed on a'central transverse line; also, that the lower portions, G, incline downward toward the edge of the shingle, so that when the shingles are laid together the portion G of one shingle will rest in the depression of part F of the next lower shingle.

Having thus described the invention, what I claim as new is 1. A shingle having struck-up portions F and G, the former being depressed on a central transverse line and the latter being inclined downward toward the edge of the shingle, substantially as set forth.

2. A sheet-metal shingle having interlocking portions and provided with a lateral horizontal flange, said flange terminating short of the end of the shingle, whereby to form astop for the adjacent shingle, substantially as set 3. A sl1eet-rnetal shingle having its edge crimped upward at right angles and then down again, forming an interlocking loop, and provided with an extension lapped within the adjacent interlocking portion and projected horizontally outward beyond the same, substantially as set forth.

4. As an improved article of manufacture, a sheet-metal shingle having struck-up portions F and G, the former being depressed on a central transverse line, and the latter being inclined downward toward the edge of the shingle, provided with interlocking portions.
